It seems like the important thing to ask isn’t whether we can know for certain if a person without a cerebellum is concious (since we don’t really know that for non-self people in general). More interesting to me is the question of if we’ve asked someone without a cerebellum if they feel concious. If the answer is “Yes, and they said they’re concious”, then I think that’s about as much evidence as we’re likely to get.
